  1. We have used Energia for TM4C123GXL for firmware development of a product. Now we want to do firmware updates in the field over USB-serial bridge to UART0. We have successfully used the serial variant of the TM4C123GXL built-in ROM bootloader with Code Composer - built apps to test the serial update process. However with the Energia-generated .bin files, the serial load works but the app does not restart correctly after the load, and requires a hard reset or power cycle to boot correctly. So I think it may have something to do with jumping to the start address after load. I have look
  2. I'm attempting to add support for a pseudo digital protocol to a project of mine. I'm attempting to implement the dShot protocol for controlling ESCs on my thrust stand, and having some issues. The TivaC doesn't appear to have very robust output control. You can see what I'm trying to do here: https://github.com/VirtualEnder/TestStandv2/blob/dev/MQTB_Thrust_Stand/hardwareTimers.ino Basically the protocol uses a modified PWM signal with each bit being 1.67us period with 1250ns representing a 1 and 635ns representing 0, basically encoding a 2048 bit throttle signal with some CRC data and a
  3. Dear Experts, now i am working with TivaC TM4C123GH6PM an energia. i never work in watch dog timer before so i was rewrite the watch dog timer example code(i get code from google) like below, #include "driverlib/interrupt.h" #include "driverlib/sysctl.h" #include "driverlib/watchdog.h" #include "driverlib/rom_map.h" #include "driverlib/rom.h" void setup() { Serial.begin(9600); Serial.println("SETUP"); MAP_SysCtlPeripheralEnable(SYSCTL_PERIPH_WDOG0); // Enable the watchdog peripheral MAP_WatchdogReloadSet(WATCHDOG0_BASE, MAP_SysCtlClockGet() * 2); // Set
  4. Hello everyone! I need editing Energia Library for more flexebility. For example, the msp430 launchpad only have one UART available if i use Energia. How can i configure other UARTs? I need at least 3 UART and I know that TivaCTM4C1294XL have 4 UARTs. Also I need an option for add a parity bit for serial communication. Thank you so much! Gino
  5. Views: 5 Hi, I have a problem with serial communication. I'm using IDE Energia to print a simple word ("hello") on the serial monitor but nothing appear (no error in the sketch). Can you help me? PS: right board and COM port are selected and serial monitor and board have the same baud rate . The code is: void setup () { Serial.begin(9600); } void loop() { Serial.println("hello"); delay(1000); } I don't know why the monitore showing nothing. Thanks for the help Gino
  6. Hello all, I#ve got issues working with i2c (in another thread) but I wonder if anyone has gotten i2c working between 2 tivac connected boards using the master_writer and slave_receiver sketches? I can't seem to get any i2c working at all with the 1.8.7e21 version of energia. Can you make it work? Cheers Sol
  7. Hey all, I've currently got an issue where i2c just isn't working with energia, I've opened an issue on github but haven't gotten any replies. Is there a better way to get some eyes on this? Would anyone here mind taking a look? https://github.com/energia/tivac-core/issues/41 Cheers Sol
  8. Hello, I am building a differential drive robot based on ROS and Tivac tm4c129xl as the embedded controller and I am using rosserial_tivac package to communicate between ROS and tivac through serial communication every peiece of code is working fine beacuse I tested them all seperately The problem is that I have two interrupts for each wheel to read the encoder ticks and send these ticks to ROS through Serial port what cause a problem that the wheels will continue rotating and the interrupt will be raised always and the program will execute the interrupt over and over again I read so
  9. I am use Energia 1.6.10E18 to build a simple application to run on a TivaC Launchpad board on a CentOS 6 64bit Linux system. CentOS 6 uses older library versions, so I needed to download and install an older GCC compiler and I got that working. Now my problem is DSLite. The version shipped with the TivaC package (dslite-7.2.0.2096-i386-x86_64-pc-linux-gnu.tar.bz2) was built with newer libraries than are installed on CentOS 6, so DSLite crashes: /home/heller/.energia15/packages/energia/tools/dslite/7.2.0.2096/DebugServer/bin/DSLite load -c /home/heller/.energia15/packages/energia/tools/
  10. Has anyone seen the : Mini-M4 for Tiva-C https://download.mikroe.com/documents/starter-boards/mini/tiva/mini-m4-tiva-manual-v100.pdf Would it be safe to assume that it could run energia? Best, C.
  11. Hello everyone, I'm trying setup pwm frequency for tiva C in Energia but failed at this line: analogFrequency(PWM_FREQ) // define PWM pins #define PWM_1 PD_6 // define PWM frequency #define PWM_FREQ 20000 void setup() { pinMode(PWM_1, OUTPUT); analogFrequency(PWM_FREQ); } void loop() { analogWrite(PWM_1, 50); } Can help me with the problem, thank!
  12. I want to interface DHT22 with TIVAC (tm4c123). Can anyone help me with the code.My code is not working. DHT22_energia.ino
  13. I have this error lately, please give some suggestion. My target launchpad is TM4C1294 and Ide is Energia 18. For your info I use this many times without any problem. I also manage to use with MSP 430 and TM4C123. Energia: 1.6.10E18 (Windows 10), Board: "LaunchPad (Tiva C) w/ tm4c129 (120MHz)" Thank you very much. Error during uploading to TM4C1294.txt
  14. Hello, I need help sending an Ethernet raw socket through my EK-TM4C1294XL (http://www.ti.com/tool/ek-tm4c1294xl). Here is what i have done so far: -> Using and modifing some NDK examples, but the problem is that i want a code in C/C++, not using a whole operating system (TI-RTOS SYS/BIOS); -> Including NDK libraries for use of it's functions and not installing the SYS/BIOS, however i am having lots of dependencies errors; -> Using Tiva C Series Ethernet examples, but they use the lwip TCP/IP protocol stack, i'm trying to send a raw Ethernet socket only; -> Using Energi
  15. Hi all, It was a real pain in the ass to find information about interfacing LP + Wiznet ethernet chip with energia so I'm here to share my work. I was looking for a library for ethernet chips from Wiznet (W5100,W5200,W5500) for TivaC series LP. The first problem I met was that as TM4C129 LP already has an ethernet.h library, I simply could not copy a new ethernet.h library for non-ethernet Ethernet_Wiznet.zip
  16. One of the new features of the beta EnergiaNG is that fact that it is now using the standard Arduino 1.6.x IDE. Unfortunately, it doesn't look like it is ready to work as a boards manager package with the standard Arduino IDE. Energia/TI likes their branding and it seems they want to keep TI boards and Arduino board from ever meeting in the same program. At the same time, I noticed a few things that are missing and instead of trying to push those into Energia. I decided to fork the tivac-core and make the changes there. I also moved away from the proprietary dslite uploader in favor of
  17. Hello! I am using Energia to program TM4C123GXL board. The program performs a primitive data acquisition with low frequency and stores it (together with timestamps) as an array in RAM. I would like to store data in EEPROM or, preferebly in FLASH. Micro-controller has 256kB flash. How can I save data there? There is flash API (flash.h and flash.c) in lm4f/driverlib/ though I am not sure even at which address range I can write/erase data? Can anybody point out to a working example? thanks for help!

    Tiva C with Keil

    I want to use Tiva C with 430boosterpack. I tried some sample example codes available in Energia. and its working good. Energia has built in libraries for 430Boosterpack and SPI. But I am using Keil for my project programming. Can i use these libraries with Keil????? I tried to make project file in Keil with these libraries and copied .h and .c file in project folder. But there are some errors like "'Unknown identifier type 'class'".
  19. I want to use ADC and Timer interrupts in Energia. For this i have to modify ISR Table. Energia has ISR table in Startup_gcc.c file. So how to modify this file to access interrupts of ADC and Timers. Or is there any Library to access Interrupts directly. Board:- TIVA C (TM4C123G)
  20. I'm using CC110L Boosterpack with TIva C. I tried example codes provided in Energia. I want to use this boosterpack for my project. And I'm using Keil for programming. So any one can provide CC110L and SPI libraries for Keil???????

  22. - INTRODUCTION Hi everybody, I want to share a library for controlling a 4-pins PING sensor (HC-SR04 ICStation) basically, although you can also control the 3-pins PING))) sensor conventional of Parallax (URL). This library is a modification of the Caleb Zulawski's library for PING))) sensors. I made basic improvements in calculations, I added a function to calculate the distance in millimeters and added the option to change the "input trigger signal" [10uS for HC-SR04 and 5uS for PING)))] - CHANGE LOG v2.1 (26/08/2014) * Fixed calculations of distance in inches. v2.0 (25/08/20
  23. Everyone knows my obsession with building an ECU for my motorcycle. I think I'm far enough along with it, so here's where I'm at. It's based on the 40 pin BP headers and I believe should be compatible with the F5529 and TM4C123 LP's and maybe more. I still have to code for it but that will come when I'm satisfied with the hardware. The BP will sit on top of this board with its USB plug facing away from the 25 pin plug, and has the I2C and SPI ports left unused which would provide for a display, data logging or other devices to interface with it. Eagle files attached as well. 4 low-i
  24. Hi, I've recently upgraded my Energia IDE to the latest release 0101E0011. I'm using the Stellaris Launchpad with lm4f120h5qr. My sample ADC code doesn't seem to work right. Worked well in the previous release of Energia. The code compiles properly but does not produce the right output. The only changes made were to change "ADC_BASE" to "ADC0_BASE" as required. I've added Serial output code for debugging purposes. The serial output produced is: 1 2 3 Code: #include "Energia.h" #include "driverlib/sysctl.h" #include "driverlib/adc.h" void setup() { Serial.begin(115200);
  25. I have run and debgged all (expect one - where a WINDOWS client was needed) Labs for TivaC LaunchPad Workshop using command-line Sourcery CodeBench and OpenOcd, on Slackware Linux. The details can be given in this list if there is enough interest.
